Once in orbit after it launches this fall, NASA's ICESat-2 satellite will travel at speeds faster than 15,000 miles per hour. Last week, the satellite's instrument began its journey toward space riding a truck from Maryland to Arizona, never exceeding 65 mph.
Drones are changing the face of turtle research and conservation, a new study shows.
By providing new ways to track turtles over large areas and in hard-to-reach locations, the drones have quickly become a key resource for scientists.
The research, led by the University of Exeter, also says stunning drone footage can boost public interest and involvement in turtle conservation.
A team led by Michigan Technological University set out to find what makes STEM integration tick. Their research--published in the International Journal of STEM Education--followed several case studies to observe the impacts of low, medium and high degrees of integration within a classroom. They found that across the board the greatest challenge that teachers face is making explicit connections between STEM fields while balancing the need for context and student engagement.
Scientists used a technology designed for the purposes of human forensics, to provide the first genetically documented case of infanticide in brown bears, following the murder of a female and her two cubs in Trentino, the Italian Alps, where a small re-introduced population has been genetically monitored for already 20 years.
Times are tough for 31 of Michigan's 45 varieties of freshwater mussels. Sporting evocative names like wavy-rayed lampmussel and round pigtoe, these residents of the state's rivers are imperiled by habitat disruption and pollution and are also threatened by climate change.
Michigan State University (MSU) scientists' recommendation to figure out the best places to focus conservation efforts: Worry about fish.
A University of Pennsylvania paleontologist has described a 5.5 million-year-old fossil species of turtle from eastern Tennessee. It represents a new species of the genus Trachemys, commonly known as sliders, which are frequently kept as pets today.
Since the pioneering description made in 1758 by Swedish naturalist and father of taxonomy Carl Nilsson Linnaeus (1707-1778), there was officially one single silky anteater species. This short-snouted, pigmy-sized anteater would then be known for its scientific name, Cyclopes didactyla, after its inclusion on the 10th edition of Systema Naturae, Linnaeus' magnum opus responsible for describing more than 4,2 animal species. It is found in tropical forests in South and Central America, as well as in the few remaining fragments of Atlantic rainforest in Northeast Brazil.
About 25 percent of older adults admitted to hospitals have dementia and are at increased risk for serious problems like in-hospital falls and delirium (the medical term for an abrupt, rapid change in mental function).
The interplay between surface-water salinity and climate change in Central New York is the subject of a recent paper by researchers in Syracuse University's College of Arts and Sciences.
Kristina Gutchess, a Ph.D. candidate in Earth Sciences, is the lead author of an article in the prestigious journal Environmental Science and Technology (ACS Publications). Her co-authors at Syracuse include Laura Lautz, the Jesse Page Heroy Professor and chair of Earth sciences, and Christa Kelleher, assistant professor of Earth sciences.
Researchers at Brigham and Women's Hospital (BWH) have discovered a new cellular and molecular pathway that regulates CD4+ T cell response--a finding that may lead to new ways to treat diseases that result from alterations in these cells. Their discovery, published online in the Journal of Allergy and Clinical Immunology, shows that administering nicotinamide adenine dinucleotide (NAD+), a natural molecule found in all living cells, shuts off the capacity of dendritic cells and macrophages to dictate CD4+ T fate.
